Does the JST contradict 3 Nephi?

The manuscript still has those lines, with some edits. The appendix stops after the new commission and the promise that God will provide.

You checked the text immediately after the excerpt. The manuscript keeps the practical teaching alongside the added instructions.

Yes, the Bible appendix is the whole JST section, so the JST replaces the teaching about birds.

The appendix cross-references the start of the KJV passage. Follow the full manuscript past that point to see the lines that remain.

The familiar English is really there. Read the first part of verse 25 too. Jesus turns to the Twelve and identifies them as his ministers.

You acknowledge the close English overlap and restore the audience context skipped by the ellipsis. The introduction and the shared wording can both matter.

Since the audience is different, we can dismiss the close wording.

A different audience helps explain some differences. The close English still calls for an account of how it entered the Book of Mormon text.

That is a real wording difference. The JST makes the prayer an explicit request that God keep us from being led into temptation. I would ask whether that clarifies what the petition means or claims to replace its original wording.

You name what changed and what we would need to establish to turn a difference into an incompatibility. The manuscripts show the wording, while the purpose of the change calls for interpretation.

The readings are the same, so there is nothing to explain.

One says “lead us not,” while the other asks God to “suffer us not to be led.” A faithful response should take that difference seriously.
